F. (Condenser Water Control provides analog output that can be used to control condenser water flow.The 0-5VDC or 0-10VDC signal increases as discharge pressure rises above a setpoint (TYP 160 psig).This should produce an increase in the condenser water flow.)G. (Shipping Less Refrigerant to enable shipping by means that do not allow shipping with refrigerantcharges installed in the unit. The chiller must be built and tested and the refrigerant removed aftertesting.)H. (Cooler Double Layer Insulation for factory installed two ¾ inch layers of closed cell cooler insulation).I. (Flow Switch shipped loose for field mounting and wiring).J. (Vibration Isolators shipped loose: spring or rubber-in-shear).K. (Alarm Bell shipped loose to be mounted remote of the chiller and wired to the common alarmcontacts by the contractor).L. (Remote Monitor Display Terminal to provide remote monitoring and enabling/disabling of the chillcontrol plus reading of all microcomputer screens).Part 3: Execution3.01 Installation Work By Mechanical ContractorA.
